Letters Patent No. 98,873. dated J a'nua'ry 18, 1870.

STOVE-PIPE mum.

The Schedule referred to in these Letters Patent and making part t thesame.

To whom it may concern:

Be it known that I, GEORGE W. Loss, of Dexter, in the county of\Vashtenaw, and State of Michigan, have invented a new and usefulImprovement in Heat- R-adiating Stove-Drums; and I do declare that thefollowing is a true'and accurate description thereof,

reference being bad to theaccompanying drawings, and'to the:lette1s oireference marked thereon, and being a part of this specification, inwhich--- Figure 1 is a vertical section of my improvement, and

Figure 2 is a perspective of the inner shell and dcflectors.

Like letters indicate like parts in each figure. The nature of thisinvention relates to an improved construction of heat-radiators ordrums, through which smoke and gases of combustion pass from the stoveto the chimney.

It consists in a. rectangular easing, into which the stove-pipe leads,and from the upper part of which it is led. Within the case is anothershell, through which the smoke may pass direct, if desired, or ascend inalternating currents between the inner and outer shells, by thearrangement of certain deflectingplates on the exterior of the innershell, which deflect it toward the outer or radiating-case, whileretaining it in its passage, to 'allow the heat to be-takcn up by saidcasing, and radiated into the apartment in which it is placed; also, inthe arrangement and method of operating the valve within the case, fordirecting and regulating the course of the heated currents through thesame.

Inythe drawings- Arepresents arrectangnlar.sheet-metal case or radiator,into which the smoke and heated currents enter through theinduction-pipe a, and whence they are discharged, through a similar.pipe, I), at the top,

into the stove-pipe proper.

B is a rectangular shell, of sheet-metal, of lesser size than the caseA, into which it is inserted In the upper part of the shell is hung orpivoted a butterflyvalve, 0, which is employed to open or close theshell to the passage of the heated currents through the same, havingattached to it a lever, c, projecting through slots in the inner andouter shells for that purpose, and which valve is thus operatedexternally, The walls of ,the shell B terminate against the inclined topand bottom of the case, except on one of the lower 7 sides, where thewall is .cut away to permit the heated currents to pass between theinner and outer shells, when compelled to take that course by theclosure of the inner shell.

D is a diaphragm or stop-plate, secured to and projectiug from onecorner of the inner shell into the adjacent corner of the case.

E are deflecting-plates, starting from the stop-plate, and extending,horizontally, nearly around the inner shell, to which they are secured.

E are similar plates, intermediately disposed between the plates E, butstart from the opposite side of the stop-plate. ,Both series of platesare "inclined upward,and are of such width, that when placedwith in thecase A,they will touch its inner walls, and, with them,form alternatingor zigzag fines, through which the heated curreutsare compelled to pass.and, as their tendency is upward, by the inclination of the plates E E,they are compelled to pass in proximity to the walls of the case, whichthereby more readily take up the heat, and radiate'it into. theapartment The rectangular form is preferable to the circular, inradiators of this description, as the currents weretarded in theirpassage more than they would be in going around a circular shell, and Iam thereby enabled'to dispense wiih a certain number of thedeflecting-plates, to make the whole of less height, and at a reducedcost. i

What- I claim as my invention, and desire to secure by Letters Patent,is-

1. The rectangular. inner shell B, provided with valve C and lever c,stop-plate D, and alternating deflecting-plates E E, as and for thepurpose set forth. 2. The combination and arrangement of the foregof ingparts within the rectangular case'A, in the manner and for the purposespecified.
